Brakes and Controls

Note: Most brake service parts are available new to order. Front and rear wheel cylinders and repair kits are in stock. Master cylinders are available in a range of sizes for servo or non-servo cars. We only stock the best types, not the cheapest! New standard and Goodridge style hoses are available for all requirements.

Despite recent price increases, we source these items in bulk so that we can pass on savings to Imp Club members.

We also stock all brake pipes in salt resistant Cunifer-10 material (10:90 nickel:copper). Clutch and fuel pipes are available in the same material. These can be made up to length for special orders, e.g. Bond 875. All components are supplied ready to fit.

Our modern high friction brake shoes are an alternative to servo or disc brakes. We can also source front disc conversions if desired.

Note: We re-condition items such as brake shoes and provide a variety of friction materials, please ask. Re-conditioned items carry a replacement warranty for six months from time of sale.

Because of shortage of good Imp rear shoes, we may supply sets which are a mix of Imp and Allegro shoes. The Imp shoes with the rectangular slot must be used for the hand brake transfer levers, the Allegro shoes have a larger irregular shaped slot. Beware some Internet sellers do not know the difference!
